A novel differential energy watermarking scheme based on FSM model against video time-space tampering

Abstract

In this paper, a video-oriented Differential Energy Watermarking scheme based on Finite State Machine (FSM) model against time-space tampering is suggested, which not only retains classical DEW algorithm's advantages dealing with space-domain attack, but also efficiently detects time-domain synchronous attack by using FSM model to produce inter-frame correlation. It is compound algorithm against time-space tampering. Experiments show that the watermarks keep robust to common intra-frame disturbance such as noise while its fragility to malicious inter-frame attack provides it effective directivity against synchronous attack. In addition, it performs well in invisibility, algorithm security and complexity. © 2009 Springer-Verlag Berlin Heidelberg.
